I have a 87 Itasca with a 2.4 Auto. I hooked up a Transmission gage (where the coin box is to the left of the steering wheel. Anyway I wanted to hook up the temp switch to the trans pan. Took it off and found that there probably is only one place it can be hooked to. (Passenger side 1 1/2 inches from the front. The part I got from Napa to screw the temp switch into had the wrong threading on it. So I decided that I would instead use a manifold to tap into the tranny line instead. These run about 45 bucks off the internet. Still have to order it. Would like others ideas on how you installed your manifold into the tranny line. I am posting some pictures of the trans and what I was up against. Also my unit has a trans cooler from the factory but are these large enough for the unit. Ted from Seattle
